Reaction Steps
Using Buchwald Procedure A, 2-chloro-7-cyclopentyl-7H-pyrrolo[2,3-d]pyrimidine-6-carbonitrile (95 mg, 0.385 mmol) and 4-(6-amino-pyridin-3-yl)-2-methyl-piperazine-1-carboxylic acid tert-butyl ester (124 mg, 0.424 mmol) gave 4-[6-(6-cyano-7-cyclopentyl-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino)-pyridin-3-yl]-2-methyl-piperazine-1-carboxylic acid tert-butyl ester (128 mg) [following SiO2 chromatography eluting with 1-2.5% MeOH/dichloromethane and subsequent trituration with diethyl ether]. The material is used directly in the next step.
